Reaction Quotient and Equilibrium Constant Practice Test

For the reversible reaction $\mathrm{CaCO_3(s) \rightleftharpoons CaO(s) + CO_2(g)}$ at a given temperature, $K_c = 0.20$. A sealed container initially has $\mathrm{CO_2} = 0.50,\mathrm{M}$ in the presence of solid $\mathrm{CaCO_3}$ and solid $\mathrm{CaO}$, and the system is not at equilibrium. (Solids are not included in $Q_c$.) Based on comparing $Q_c$ and $K_c$, in which direction will the reaction proceed to reach equilibrium?

For the reversible reaction $\mathrm{2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)}$ at a given temperature, $K_c = 1.0\times 10^2$. A mixture is prepared with initial concentrations $\mathrm{SO_2} = 0.10,\mathrm{M}$, $\mathrm{O_2} = 0.10,\mathrm{M}$, and $\mathrm{SO_3} = 1.0,\mathrm{M}$, and the system is not at equilibrium. Based on comparing $Q_c$ and $K_c$, in which direction will the reaction proceed to reach equilibrium?
